Enhancing Meeting Etiquette: Disabling Chat Write Access for Anonymous or Unauthenticated Users in Microsoft Teams

Microsoft Teams has revolutionized the way we collaborate and communicate in the workplace, enabling seamless virtual meetings with both internal and external participants. However, the presence of anonymous or unauthenticated users can occasionally lead to challenges, particularly when it comes to maintaining a professional and respectful meeting environment.

To address this concern, Microsoft has introduced a valuable feature that allows Microsoft Teams administrators to disable chat write access for anonymous or unauthenticated users, effectively minimizing the possibility of inappropriate content jeopardizing meeting discussions.
